Fish wholesaler Kazuo Takeguchi, 71, said he had had hopes for Koike's party but was disappointed when she decided not to run. Instead, he voted for the Japanese Communist Party, in part because of the cronyism scandals that had eroded Abe's ratings.
"I can't help wonder if you are entitled to do whatever you want to if you are sole strong party," Takeguchi said.
"I want some party to emerge as a force to defeat the LDP," he said, adding, however, that the JCP was unlikely to play that role.
A new Constitutional Democratic Party of Japan (CDPJ), formed by liberal DP members, is now vying with Koike's party for the top opposition spot, though both will have just a sliver of the LDP's presence if forecasts prove accurate.
